Abstract :
In this article, the monitoring and measuring of the Xuejiazhuang tunnel of Lingnan freeway is introduced. The fitting regression analysis for the data of curve was done. And the surrounding rock stability is studied with the regression analysis of the convergence displacement data. In order to maintain the existing void between initial lining and surrounding rock, the ground-penetrating radar nondestructive testing technology and polymer grouting technology is presented. The field test results show that the use of polymer grouting technology can repair the tunnel distress and provide an ideal manner for tunnel quick maintenance.
